William Linz

In this note, we study two generalizations of the Catalan numbers, namely the $s$ -Catalan numbers and the spin $s$ -Catalan numbers. These numbers first appeared in relation to quan…

Short proofs of three results about intersecting systems

József Balogh, William Linz

In this note, we give short proofs of three theorems about intersection problems. The first one is a determination of the maximum size of a nontrivial $k$ -uniform, $d$ -wise interse…
